Title: Adjustable probe support structure
IPC: G01M99/00
Filed: 1975-04-14
Abstract: 1505675 Eddy current sensor CARRIER CORP 14 April 1975 [28 May 1974] 15212/75 Heading G1N An eddy current sensor includes a probe support structure 10 having a housing 17 to which a bush plate 21 is secured by screws 22, into which plate the shank 25 of a probe holder 14 is screwed. The shank has opposed parallel flats 27, 28 received in a slot 32 in an adjusting washer 31 from which a dowel 40 projects whereby the probe holder is screwed into or out of the plate 21 to vary the gap between the probe 13 and a machine rotor 15 which is to be sensed. In use the probe is moved into contact with the rotor and then withdrawn a predetermined distance so that the gap is at the mid-point of a range over which the gap vs. voltage output of the sensor is linear. Rotary movement of the dowel is limited by stop pins 38, 39 secured in the plate. Thus the scale factor of the sensor is determined by displacing the probe holder so the dowel moves from one stop pin to the other and determining the change in voltage output from an R.F. generator to which the probe is connected via cable 12. The housing is fixed to the machine casing by a threaded sleeve 18.

Title: Improvements in and relating to web feeding devices
IPC: B65H27/00
Filed: 1947-06-11
Abstract: 623,969. Feeding - apparatus for webs. COURTAULDS, Ltd., and BURDIN, N. V. June 11, 1947, No. 15338. [Class 100 (i)] A device for straightening the edges of a web of fabric &c. while being fed to a machine such as a tentering machine is constructed so that each edge of the web, which may be subjected to a rough preliminary straightening, is passed over a drum 1 fitted with a series of feelers 16 and associated retractable pins 19 which are caused to pierce the material at a fixed distance from the edge of the web, and the feelers and associated pins are then moved and held on a fixed path. A drum 29 moves with the drum 1 and is fitted with a series of clamping devices 34 which are caused to press on the edges of the web while the feelers 16 act upon the web so as to prevent cockling of the web. The feelers 16 are carried by bars 6 which are moved in a direction parallel to the axis of the drum 1 by means of a fixed cam surface 9 against which balls 8 at the ends of the bars 6 are pressed by means of springs 7. As shown in Fig. 1, the drum 1 is adapted to act upon the left edge of a fabric, the right edge of which is controlled by a similar drum with feelers and pins which act on the right edge of the fabric, the second device being a mirror image of the one shown in Fig. 1. The fabric contacts the drum at the position A, Fig. 2, its edge being to the right of the feelers 16. Prior to the engagement of the edge of the web with a feeler, the clamps 34 are moved to grip the web lightly, which operation is completed at position B. The feelers are then moved by the springs 7 to the right and by the time position C is reached the feelers 16 are either at the end of their slits 15 or held by engagement of the web at an intermediate position. At position C, a cam 22 raises the pins 19 against the action of springs 20, and the web is gripped at a definite distance from its edge. This action is completed at position D and the clamps are then released and at position E the web leaves the drum 1. The clamps 34 are actuated by pivoted arms 33 connected to bars 35 which are reciprocated in grooves in the drum 29 by a cam groove acting upon a roller 38 connected to a sliding block 39 having. a yielding connection with the bar 35. The registered web is fed to stentering chains 55, Fig. 4, by means of friction rubber rollers 52, 56 which tend to tension the web longitudinally, and the edges of roller 52 are each formed with an annular brush 53 which forces the edges of of the web upon the pins 54 of the stentering chain. Specification 542,323 is referred to.

[Also in Groups XXXII and XXXIV] For retarding the movement of a wheeled vehicle, a rocking device 27 is positioned in the path of the wheels 39 of the vehicle so as to be rocked by the wheels, energy being dissipated in an hydraulic dashpot device 11. The rocking device 27 is provided with a ball-and-socket bearing 33, 34 with the dashpot device 11 secured to a track rail 14. A toothed portion 30 integral with the ball element 33 extends into a slot 31 of a double-headed piston element 21 acting in a chamber 17. The two cylinders 20 of chamber 17 are interconnected by a duct 23 with an adjustable throttle valve 24 to regulate the flow of hydraulic fluid from one cylinder to the other. The dashpot is filled with hydraulic fluid to the level indicated at 38 and a flexible gaiter 35 prevents the egress of fluid from or the ingress of dirt into the housing. When a vehicle passes, the wheel flange 39 engages the elevated rocker finger 32 and depresses it, causing the rocker device to force piston element 21 in one axial direction along chamber 17, the piston element being retarded in its movement by the hydraulic fluid. When the initially elevated rocker finger 32 has been depressed the other rocker finger 32 will automatically be elevated into the path of the same or a succeeding vehicle wheel, the rocker device 27 being again operated to move piston element 21 in the opposite axial direction for the other piston to be actuated. If the throttle 24 is closed, the rocker device may be locked, in any desired position, to provide a chock for a vehicle wheel.
